LAMP-CHIMNEY HOLDER.

To all whom t may concern.'

Be it known that I, FRANK W. LrNs'rRoM- BERG, a citizen of the United States, residing atk Bourbon, State of Missouri, have invented certain new and useful Improvements in Lamp-Chimney Holders, `of whichV the following is a specication; j

My invention relates to lamps, and more particularly to improvements for securing a lamp chimney in: position adjacent the burner.

'The primary object of my invention is toA provide a simple, cheap, and durable clampingband for assisting in the retention of a lamp chimney in position.

further object o f my invention to provide a device ofthe above mentioned character whichmaybe easily and quickly placed in t removableV andY applicableV to almost anyv position, and one which is readily size of lamp. t

A still further object of my invention-is to provide an improved 'clamping means associatedv with the retaining band-which facilitates the convenient disposal and retention ofthe device onA a 'lamp chimney for ing member which will automatically lock the same against accidental Ydislodg'mentV from clamped position. Y

IVith the above and other objectsv inview my invention resides'preferably in the construction, combination, and arrangement of parts'as hereinafter setrforth in the specication andl illustrated in theaccompany-l ing drawing, in which-1'. Y Figure l is a side elevation of a lamp burner and chimneyshowing my improved retainer in position. Fig.VV 2 is atop plan view' of the same, the lamp chimney being shown in section and my invention being fragmentarily indicated. Fig. 3 is a plan View of the improved clamping member. Fig.4 is a longitudinal sectional view taken on the line H of Fig. 3. Fig. 5 is a transverse sectional view taken on'the line' 5 5 of Fig. 3`.

In the drawings the numeral Vl indicates the base of an ordinary lamp .burner 2, the said lamp burner 2 having the usual resilient arms 3 extending vertically therefrom'rfor embracing the base 4 of the ordinaryV lamp spring 5' extending substantially completely around thebase 4 of the lamp chimney Yand Patented Feb. 15, 1916. n Application mea March 15,1915. seriai N. 14,499'. y

adapted to inclose in its embrasure the resilientarms 3. rInhe opposite extremities of the band 5 are connected, respectively, to Y the movable and stationary 'elements ofmy Y clamping member, described in detail hereafter. I have found that the disipositionof the band 5f as shown in Fig. 1 is preferable,

since this isVvappro-ximately the Vpoint at which the arms 3 usually engage the chimneyf base 4:;

My improved clamping device comprises a strip of vbendable metal 6 having-the marginal edgesv bent to form longitudinally disposed and laterally extending flanges? and 8,l forming as a whole a 'channel member.I The strip 6 is extendedY as at 9 and apertured as at l0 for reception of 'one extremf ity of the band 5 which is preferably formed A with-ailoopl 11 for engagement in the aperture 10. Thestrip 6 is provided adjacent its oppositel extremity with Van elongated aperture l2. Upon' reference to Fig. 4, it`

will be noted that a portion ofthe-strip 6 is depressed from the plane of the main'por'- tion of thestrip k6 as shownat 13 to providea guide or runway for the spring 5, this functionA being brought out. more fully hereinafter. Owing to this peculiar formation, it will be noted thatl the flanges 7 and 8 converge slightly as indicated at ltwhi'ch performs a function which will be 'hereinafter set forth. A pivotedlever is provided whichcomprises a strip or plate-'15 of bendable metal, said platelhaving a pair of oppositeiy 'excendiaglateral prejectias 16 free extremityV of lthe Vplate 15 is enlarged'` as shown at 19 and outwardly bent as at 20 to provide aV handle.

Upon reference to Fig. 5 it will be noted that the width of the plate 15 is such that the same when in locked position will snugly engage the flanges 7 and S for a purpose which will hereinafter appear. rIhe inner extremity of the plate 15 is recessed as shown at 21,to receive the portion of the band which is adapted to lie therein when the device is in clamped position. One extremity of the band 5 being secured to the extension 9, the opposite extremity thereof is then secured to the arm 15 at a point substantially intermediate its length, this 4ex-` tremity ofthe band 5 being looped as shown at 22, and the plate 15 being provided with a. struck-up portion 23 for engagement with the loop 425%,.as shown to advantage'in Figs. 3 and 4.

In order to lock the arm 15 in clamped po.- sition, theflanges. 7 and 8 are depressed inwardly from their outer marginal edges to provide locking abutments 24,1which owing to the inherent resiliency of the material utilized will allow of reception of the arm or lever 15 ,between the flanges 7 and 8, to allow for a. tendency to prevent its withdrawal from all accidental sources.-

From the above description taken in con nection with the accompanying drawings, it is thought that a clear and comprehensive understanding of the construction, use, and

Vadvantages of my invention maybe readily In use the base 4 of the lamp gathered. chimney is placed in position in the 'usual manner, andthe resilient bandy 5 slipped over the top of the same and moved into the position shown in Fig. 1. During this operation the lever 15 should bein a releasedposition indicated in dotted lines at 25 in Fig. 4.V When the lamp chimney has been disposed in position and the band in its respective position, the arm 5 is moved into the clamping position shown in the drawings until the marginal edges thereof engage under the locking abutments Q4, and at this time it `will be found that the lampchimney is rigidly held in position. Accidental vibration or other movements of the clamping mechanism will not dislodge the same owing to the engagement of the arm 15 with the locking abutments .24. 1When in clamped position it will be readily understood that the band 5 is in the distended'position so.

that at all times secure clamping.engage-l ment with the arms 3 is afforded and that accidental dislodgment of the vlamp chimney is practically impossible under ordinary conditions. I desire to lay particularstressi on the peculiar construction of the clamping.,` member, and while I have shown the invena tion as applied to the function of `retaining a lamp chimney in position, it will be read-i 70 ily understood that the scope of its uses is Y not limited.:y

W'henthe device is in locked position, the spring 5 will be received on the runway 13, which, owing to its peculiar formation, will prevent accidental dislodgment of the spring. Should the same become dislodged from any reason, the flanges -7 and 8, converging as at 14 willhave a tendencyfto 4re-i turn the spring to the position shown.

l/Vhile I have shown and describedmy ,infv vention as possessing a pecnliar form and construction, it is desired that it be understood that I may make. such changes in the details thereof that do fnot depart Afrom the spirit, and scope of the invention as claimed.

Having thus described my invention what I claim and desire'torsecure byLetters Pat-fent is:

1. A lamp chimney holder, including a ref silient band, a clamping member comprising z a channel, a lever pivoted f'therein, the ex.-` tremities of said band being connected to the channel and lever, and `meansin said chan! nel to retain said lever inclamped position. Y
